The Securities and Exchange Commission is proposing new rules and forms as well as amendments to its rules and forms to modernize the reporting and disclosure of information by registered investment companies. The Commission is proposing new Form N-PORT, which would require certain registered investment companies to report information about their monthly portfolio holdings to the Commission in a structured data format. In addition, the Commission is proposing amendments to Regulation S-X, which would require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The Commission is also proposing new rule 30e-3, which would permit but not require registered investment companies to transmit periodic reports to their shareholders by making the reports accessible on a Web site and satisfying certain other conditions. The Commission is proposing new Form N-CEN, which would require registered investment companies, other than face amount certificate companies, to annually report certain census-type information to the Commission in a structured data format. Finally, the Commission is proposing to rescind current Forms N-Q and N-SAR and to amend certain other rules and forms. Collectively, these amendments would, among other things, improve the information that the Commission receives from investment companies and assist the Commission, in its role as primary regulator of investment companies, to better fulfill its mission of protecting investors, maintaining fair, orderly and efficient markets, and facilitating capital formation. Investors and other potential users could also utilize this information to help investors make more informed investment decisions.
